Biomass of cover crop mixtures planted at two planting dates in a statewide cover crop trial. Biomass was measured in November 2009 at 11 sites throughout Pennsylvania. In the graph, the bars represent cover crop biomass averaged across 8 to 11 sites that were sampled for each mixture. The lines represent the range from the least to the greatest biomass measured for each mixture across the sites. For more information, contact Ron Hoover at Penn State: rjh7@psu.edu or 814-865-6672.

Biomass of cover crop mixtures planted at two planting dates in a statewide cover crop trial. Biomass was measured in late April and early May at 11 sites throughout Pennsylvania. In the graph, the bars represent cover crop biomass averaged across 5 to 11 sites that were sampled for each mixture. The lines represent the range from the least to the greatest biomass measured for each mixture across the sites. For more information, contact Ron Hoover at Penn State: rjh7@psu.edu or 814-865-6672.
